Elvis 6 API - authcred

Elvis 6 API - authcred

Append to URL

?authcred=<base64Encode( username + ":" + password )> [&authclient=api_...]

What does it do?

It can be added to a URL to authenticate the request with the provided credentials.


  • Authcred authentication does not support the ability to modify data; only retrieving data (GET/OPTION/HEAD requests) such as downloading assets is supported. Integrations that want to modify data should use another form of authentication.

Warning: When you add an authcred to a URL, it is trivial for others to decode the credentials and retrieve the password. For this reason you should only use it for material that is 'public'. In most cases this means you should create a public guest account with very limited permissions.

When to use?

Adding an authcred to a URL can be useful when you want to publish or distribute URLs to Elvis content. For example to:

  • Publish assets from Elvis directly on the web.
  • Insert URLs for asset previews in your web CMS.
  • Publish links or QR codes that link directly to content.

Client type

An optional authclient can be specified to track which interface was used to perform operations logged in the asset usage history. The client type must be prefixed with "api_", for example: "api_MyPublicWebsite".


Note: All examples use an authcred for the guest:guest user that can only see public material.
